That is history and politics.
60 Hertz
If the appliance is 220 volt 60 Htz, yes it will work perfectly in the U.S. plugged into a 240 volt outlet.
It depends on the country as to which voltage is used for industrial purposes. In the US, for welding for example, voltage may be 480 volts. The frequency in the US is 60 Hertz.
The voltage specification for a US electrical outlet is 120 volts, and the frequency specification is 60 Hz.
In the US AC current oscillates at 60 Hz.http://www.answers.com/alternating+current
AC, alternating current is used to power electrical outlets in the U.S..
the voltage and frequency are 110v and 50(or)60hz because the devices which are invented in us are work at that voltage and it is efficient for that devices.
Different video coding.
Assuming the frequency of Middle C to be 261.63 hertz, accurate to two decimal places, taking this two octaves down brings us to 65.41 hertz. Sending us down a further semitone gives us 65.41 x 1/21/12, which sends us to B, at a frequency of 61.74 hertz, accurate to two decimal places, the closest possible genuine note to a 60 hertz frequency. Effectively, this is the third B below middle C, including that which is a semitone below.
it depends on the CPU.. but the frequency is measured in herts
yes, but you need an adaptor because US plugs are different to UK plugs you can get these adaptors from places like Maplins ********************************************************************** Some appliances can be operated on either 50 or 60 hertz. It is preferable to use the frequency that the appliance was designed for. Some appliances have a switch which can be activated so that the appliance can be used at the alternate frequency.
Voltage does not have a waveform. The waveform is based upon the frequency of the voltage or current. A battery (any voltage) does not waveform, however the voltage coming into your house (US) has a frequency of 60 Hz. The length of the 60 hz waveformLength (in centimeters) = (3 x (10 ** 10))/ Frequency in hz =500 000 000 cm
